I have had this test run three times, once with my old ECU which had a fault causing a slight miss-fire, secondly with my new ECU as standard and thirdly with my superchipped new ECU. I think this tells me that its got nout to do with the ecu. Would the two lambda sensors cause this or are there any other factors?
From what i can remember, on emmisions test if it failed. It used to mean the lambda was blocked, if you have done alot of around town journeys, that wouldn't help. Give it a damm good thrashing or some high revs to clear it out.
